Here mine, It has a bolt on pulley and easily changed between 1-4 stages(moduler) The first one had 100hrs on the bench before it went on the boat and ran great till I spun it to fast and smoked the impellers(only damage)[img]

I don't have any upto date pics of the new pulley and hoses as I dual feed the pump now, and everythings is AN fittings but this is what it looks like sitting in the boat.

mercury GEN IV sea pumps. There is 2 versions - Merc part numbers. I would have to relook at the part numbers on the boxes as I can not recall them at the moment.

Both are bolt on pulley versions GEN IV pumps.

post 21 who pump is that ?? Hardin Marine duel stage ?

Its my own design, I designed, machined, and tested it(100hrs at 4k rpm) before it went on the boat. It used standard Bravo 1 impellers.

Oh ok you didnt adapt anything you legit made a dual stage pump, nice! Im assuming your a machinist/CNC operator durig the day? Haha

So your thinking the typical Bravo impeller wont be able to feed enough raw water to the block/oil coolers factory stuff etc AND whatever I end up using for the blower heat exchanger?

Kinda of, I design, fabricate, and test concept vehicles for the leader in powersports, so something like a water pump is somewhat simple for me.

I think you would be pushing your luck trying todo it all, not saying it cant be done but with the RPM range a LS motor runs you will have a harder time cooling at idle as you will need to spin the pump slower so you don't over spin it at High RPM.

That and you want cold unrestricted water flowing thru your intercooler, so by the time you pass thru the intercool, heat exchangers, manifolds, and exhaust its pretty restricted.


I could always build you one

That's correct I just looked at the boxes I have in stock to confirm the part numbers.

GrannySShifting

That would be awesome, but Id need two, and Im afraid to ask LOL. Budget has already gone wayyy out of proportion

GrannySShifting

What the difference in those and the ones I found? Uses same impeller right? I guess he could be using **** bearings, but that could be swapped out, what other issues have you seen BUP?

turbom700

Single or 2 stage?

I here you about budgets, I thought it would be nice todo all AN fittings and hose for my water lines so they look nice and are easy to unhook. 2k later I was done
